This could well be your refresh rate. Move your mouse pointer over any blank area of the screen and right click. Highlight and click on properties.Click on the settings tab, then on advanced then on to the monitor tab. You should see a setting for refresh rate eg. 75 Hertz. Change the refresh rate and the noise should disappear.

Emits high pitched whistling after unit runs for 30 minutes

Sounds to me like the bearings are going bad in the motor. The hotter it gets the grease breaks down and the squealing starts.

Tv makes high pitched humming noise

A high pitched humming noise is an indication of a ground loop, or a circuit gone bad in side the TV. I recommend taking it to a repair shop. This isn't something you can fix yourself.

Philips HTS3450 - high pitched humming noise until warmed up

Jeremy,

Read one of my posts:
I used a hairdryer and blew hot air into the grill on the bottom of the subwoofer enclosure which reduced the delay time from ~1hr to 5 minutes. (The high pitched noise was still there for about 1-2 minutes)

All three lights turn on like normal and then nothing

Depending on the pitch. humming noises are either a motor ie: fan motor or if it is very low a defective capacitor . Since you have the yellow band and the high pitched beep my fist thought is somthing defective in the power supply. Take it to an authorized servicer.

Monitor making humming noise

First try moving speakers away from monitor a bit. Some speakers magnets actually reduce the life span off monitor. I hope I am wrong but usually a high pitch whine is the High voltage Transformer. Costs more than the monitor. All you can do is continue use till it goes. Speakers usually deteriorate the tube itself. HVT are just one of those parts that go due to use. Hope it gives you more enjoyment before it goes. Good luck and try to have a good day.
